/* ============================================================================
   待执行 v2 · 样式（珊瑚橙品牌 hero + 四象限统计 + 任务卡 + 三类弹层）
   ----------------------------------------------------------------------------
   设计：扁平化纯色（无 gradient），珊瑚橙 var(--brand) 为主品牌色
        + 任务卡多态（pending/progress/done/overdue）+ 倒计时档位色阶
        + 学习/考试弹层（SVG ring 倒计时、单/多选题、答题详情）
   布局：移动端 .tasks-page 12/14px 内边距；hero 珊瑚橙；2x2/4 列象限网格；
         内容区底部由 .app-content 留白避开浮动 tabbar
   弹层：.sheet-mask 已由 core.css 定义；本文件补充 .sheet（底部上滑）
         + .sheet-btn 的 ghost/primary/disabled 变体（业务定制）
